PURPOSE:To easily join aluminum materials at a high speed regardless of the shape of joining part even when the materials are highly sensitive for solidify cracking. CONSTITUTION:In a joining method for aluminum members, a joining surface 2 of at least one of two aluminum members to be joined 1 is flame sprayed with Al-Si alloy filler metal to form a coating film on it and the members 1 are combined and joined by laser beam welding. Thus, the welding posture is not limited. |
